Exam 22: Early Development of the Plant Body

Which of the following CANNOT be part of the plumule?

Which primary meristem forms first?

The suspensor anchors the embryo at the micropyle.

The apical meristems are the source of virtually all of the tissues of the seedling and adult plant.

The process of after-ripening involves:

The scar left on the seed coat after the seed has separated from its stalk is called the:

In temperate regions of the world, after-ripening is triggered by:

In a grass embryo, the coleoptile encloses the plumule.

The suspensor is an example of a structure that undergoes programmed cell death.

When the zygote first divides, the two daughter cells are the ______ cell and the ______ cell.

The root and shoot apical meristems are two of the primary meristems.

Metabolism increases toward the end of the maturation phase of seed development.

The cotyledons elongate most dramatically and may become curved during the _______ stage.

The ______ is usually the first structure to emerge from a germinating seed.

The dormancy acquired during seed maturation is called primary dormancy.

Located at the micropylar pole of the embryo is the:

The stem-like axis above the cotyledon(s) is the:

In eudicots, in which most of the endosperm is absorbed by the embryo, the cotyledons:

Which of the following statements about seed germination in onion (Allium cepa) is FALSE?

In temperate regions, after-ripening ensures that seeds will germinate in the fall rather than in the spring.
